30# Script to simplify using rundiff on trace outputs from two
31# invocations of m5.
31# invocations of m5. Takes a common m5 command line with embedded
32# alternatives and executes the two alternative commands in separate
33# subdirectories with output piped to rundiff.
32#
33# ******Note that you need to enable some trace flags in the args in order
34# to do anything useful!******
35#
36# Script arguments are handled uniformly as follows:
37# - If the argument does not contain a '|' character, it is appended
38# to both command lines.
39# - If the argument has a '|' character in it, the text on either side
40# of the '|' is appended to the respective command lines. Note that
41# you'll have to quote the arg or escape the '|' with a backslash
42# so that the shell doesn't think you're doing a pipe.

38# Script arguments are handled uniformly as follows:
39# - If the argument does not contain a '|' character, it is appended
40# to both command lines.
41# - If the argument has a '|' character in it, the text on either side
42# of the '|' is appended to the respective command lines. Note that
43# you'll have to quote the arg or escape the '|' with a backslash
44# so that the shell doesn't think you're doing a pipe.
45# - Arguments with '#' characters are split at those characters,
46# processed for alternatives ('|'s) as independent terms, then
47# pasted back into a single argument (without the '#'s). (Sort of
48# inspired by the C preprocessor '##' token pasting operator.)
43#
44# In other words, the arguments should look like the command line you
45# want to run, with "|" used to list the alternatives for the parts
46# that you want to differ between the two runs.
47#
48# For example:

49#
50# In other words, the arguments should look like the command line you
51# want to run, with "|" used to list the alternatives for the parts
52# that you want to differ between the two runs.
53#
54# For example:
55#
50# % tracediff m5.opt --opt1 "--opt2|--opt3" --opt4
56# % tracediff m5.opt --opt1 '--opt2|--opt3' --opt4
51# would compare these two runs:
52# m5.opt --opt1 --opt2 --opt4
53# m5.opt --opt1 --opt3 --opt4
54#
57# would compare these two runs:
58# m5.opt --opt1 --opt2 --opt4
59# m5.opt --opt1 --opt3 --opt4
60#
55# If you want to compare two different simulator binaries, put a '|'
56# in the first script argument ("path1/m5.opt|path2/m5.opt"). If you
57# want to add arguments to one run only, just put a '|' in with text
58# only on one side ("--onlyOn1|"). You can do this with multiple
59# arguments together too ("|-a -b -c" adds three args to the second
61# % tracediff 'path1|path2#/m5.opt' --opt1 --opt2
62# would compare these two runs:
63# path1/m5.opt --opt1 --opt2
64# path2/m5.opt --opt1 --opt2
65#
66# If you want to add arguments to one run only, just put a '|' in with
67# text only on one side ('--onlyOn1|'). You can do this with multiple
68# arguments together too ('|-a -b -c' adds three args to the second
60# run only).

69# run only).
70#
71# The '-n' argument to tracediff allows you to preview the two
72# generated command lines without running them.
